What DSIP is
A naturally occurring peptide studied for sleep, stress resilience, and pain, with limited and inconsistent human evidence.
DSIP is a nine-amino-acid peptide first isolated for its ability to promote sleep-related brain activity in animals. Research has explored roles in sleep regulation, stress and cortisol modulation, and pain, but human studies are limited and results are inconsistent.
Mechanism: Proposed to modulate sleep-related neural activity and stress hormone regulation, though its exact receptor targets remain unclear.
Regulatory history: Not FDA-approved. PCAC voted against recommending it for compounding (July 2026)
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for DSIP at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
